Experimental Oscillator Strengths in the C2(A1IIu-X1 sigma g+), 1) Phillips Band System

Ab initio Cl calculations of the transition moment for the B′2Σ+–X2Σ+ transition in MgH are reported. Theoretical values for the Franck–Condon factors, band strengths, band oscillator strengths, and transition probabilities have been computed for MgH and MgD. An analysis of our results for this system predicts many bands to be observable which have not yet been identified. Dipole moment functions and vibrationally averaged dipole moments are given for the X2Σ+, A2Π, and B′2Σ+ electronic states.

Swan Band

The rotational line intensity, partial band intensity and peak band intensity methods (the latter used in conjunction with computer-generated synthetic spectra) have been used to interpret photoelectric and photographic measurements on the astrophysically important C 2 Swan band system, stably excited in a direct current discharge through C 2 CI 6 + A. All measurements lead to a consistent (within 5% ) expression for the variation of the electronic transition moment with internuclear separation of R e (r) = C (1.00-0.25r) 1.120 < r < 1.488 A . Critical assessment of recently published oscillator strength measurements on the (0,0) band suggest that C is 13.02 x 10 -18 cm e.s.u. ( ± 25 %). A table of absolute band strengths, oscillator strengths and Einstein A coefficients has thus been calculated.
